Abstract

Die Erfindung betrifft einen Kolben (40, 40', 40", 40'"), welcher entlang einer Längsmittelachse (68) axial verschiebbar in einem Zylinder (92) derart aufnehmbar ist, dass er einen ersten Zylinderraum (64) und einen zweiten Zylinderraum (66) voneinander trennt, welcher (40, 40', 40", 40'") eine umlaufende Ringnut (42) mit einer näherungsweise rechteckförmigen Querschnittsgeometrie aufweist, in der ein Dichtring (50, 51) einsetzbar ist, der mit seinem freien Ende an die Innenmantelfläche (90) des Zylinders (92) anlegbar ist sowie nach dessen Einsetzen in die Ringnut (42) des Kobens (40, 40', 40", 40"') zusammen mit wenigstens einer Nutwand (44, 46) zumindest einen Druckunterstützungsraum (52; 54) begrenzt. Der Kolben (40) weist im Bereich seiner Ringnut (42) wenigstens eine axiale Öffnung (38, 39; 70, 72) auf, welche den zumindest einen Druckunterstützungsraum (52; 54) mit dem zugeordneten ersten oder zweiten Zylinderraum (64, 66) verbindet.
